Not quite done yet but here is where it is at thus far. I couldn't find Mark's "Best" graph from before but at 8psi is here a comparison:

Red: Entry-level Kit
Blue: GT3586

EDIT: Once she is 100% done I will do a few over-lays of various Supercharger Kits and SC + Cam set-ups etc etc.

This is exactly what I want

I'm still impressed

If it doesn't quite equal the number (Of our GT35R-based Kit) it will get very close once boost is the same and tuning is done. Then we are going to add a cat-back just to see how much the stocker is hurting power.

Auto's make quite a bit less so the 6-speed car we do next will jump that number up quite a bit (Should be up 50ish at the wheels).

Jeff--If you have the entry level kit and wanted more power, how hard would it be to upgrade to the ball bearing/billet Garrett turbos? Would it be as easy as changing the turbos and downpipes out or would there be more to change or fabricate? Also would a boost controller help spool the turbos up faster? Thanks.

wow.. this is amazing:bow:.. do you a m6 car to test with? i know where one is ;)

^^^^^^^^
second this!
Ohio would be a nice 8 hour drive there and an amazing 8 hour drive home lol

Looks like I picked the right time to come back to C5 :happyanim: Nice work gentlemen!

On another note, is the T3 the only option? Could the downpipe be 3" on the T3? Asking because I have a 3" exhaust.

This kit is T3-flanged and 2.5" off the turbo but will still work fine for those having any a/m 3" cat-back systems. Our other kit offers V-band and 3" downpipes by comparison. The power ceiling will be lower for sure but as long as testing continues to go well that ceiling is looking like it will still be plenty high for 95% of FI buyers right now (SC or TT).
Jeff

If I would have seen this a few months ago before I started building mine I would have considered this. Looks good. Maybe I missed it but what size are the base turbos?

Does this kit come with any tuning?
 

maybe I missed it somewhere but does this kit come with any canned tuning? It would be for a short while but my tuner is 180 miles away and it would be nice to have a nice fat tune to keep everything together on a three hour drive. Thanks.

Car is 100% bone-stock Auto with just the TT Kit.

Just for testing, we wanted to see what a Cat-back would add (And also what the stock Auto exhaust was robbing since it is VERY restrictive) so here are the numbers with the cat-back removed:

Here is the over-lay with and without the stock exhaust:
